The ambient energy harvester market is anticipated to witness significant growth over the forecast period on account of rising in demand for micro power production for charging thin film batteries. The product is environment-friendly and provides clean energy. Growing demand from sensors and wireless sensor network is likely to propel demand over the forecast period. In addition, increasing utilization of the product in security equipment and electronic devices is projected to impact the industry positively over the next seven years.
Growing concern regarding environmental pollution has led to increased preference for the product over batteries in low power electronic systems. Moreover, ambient energy harvesters are more convenient as they do not require procuring, installing and changing batteries. The energy harvested is sufficient to power wireless sensor networks, which is expected to propel growth.
Key technologies include oil field monitoring systems, wireless light switches for use in smart buildings, wireless train measuring systems based on vibration, oil field monitoring systems and wireless sensors to be implemented in smart cities. Wireless sensors are self-powering and offer a broad range of functions. They are used to alert and detect pollution levels, temperatures in building, movements around patrol border areas, forest fires, and robbery.
The product utilizes various transducers including electrodynamics, piezoelectric, thermovoltaic and photovoltaics to convert energy from one form to another. The photovoltaic system employs solar energy to develop electric power.
Technical innovation has resulted in the increased performance of the harvesting devices, by reducing losses during transformation. This technology is being increasingly used as a substitute source of primary power sources which is expected to facilitate energy security worldwide.
Energy storage device market is being transformed simultaneously to capture harvested power. Key storage device technologies include thin film batteries and super-capacitors which are low cost and have high-efficiency levels. These devices play a significant role to meet high demand during peak hours. For energy harvesting to have an impact, storage devices need to match the need as well as the supply during peak hours.
The increasing acceptance of renewable sources, need to reduce carbon emissions, and stringent energy security standards set by the government across the world is expected to propel the demand for these technologies. These technologies are supposed to have tremendous opportunities in powering of portable electric devices and long-term energy storage over the next seven years.
Europe is projected to dominate the ambient energy harvester market over the forecast period. The European Commission has been investing increasingly in research and development to propel energy security in the region. North America & Asia Pacific markets are expected to grow at a rapid pace on account of rising concerns over energy conservation. The U.S. defense advanced research project involves the development of combined energy production and storage systems for application in portable weaponry, vehicles, and electronics.
Fujitsu, Honeywell International Inc, Siemens AG are key companies in the global market.
Voltree is involved in harvesting energy from trees and transforming it into electricity; that can power sensor networks to detect and control forest fires.
Piezoelectric generators created with crystals that produce power under pressure are still being tested for use in sports stadiums, walkways, and roadways to generate usable energy from traffic and activity above them.
Israeli company, Innowattech has placed PE generators below 33 feet highway and can generate power for 250 homes.
These techniques reduce the dependence on battery power and produce a free source of energy. Rising government support in various economies for energy harvesting and storage is expected to drive the market growth. Nanotechnology innovation in the field of energy harvesting is expected to reduce the size of the devices and make them more portable. However, high setup costs and lack of knowledge among people regarding the collection concept may hamper the growth of the market.
Recent innovations include harvesting of energy from the sound of heartbeats through the chest and transforming it to electricity to run implanted devices such as a pacemaker. It helps in removing the periodic need for replacement of the battery. Research is also being undertaken for harvesting body heat, movement and vibration of the body to power different implantable devices.
